yard, the length of the street being 1764 feet, and the

breadth 56% feet? (6) What is the content of a piece of wainscotting in square

in which are three windows, each 6 feet high, and 3 feet 5 inches wide, and the fire-place 4 feet by 4 feet. I demand how many yards of paper, half-yard wide,

will hang it? (8) If my court-yard be 47 feet 7 inches square, and I have

laid a footway of Purbeck stone 4 feet wide, along one side of it, what will paving the rest with flints come to

at 6d. per yard square ? (9) A rectangular four-sided room measures 1291 feet about,

and is to be wainscotted at 3s. 6d. per yard square; after the due allowances for girt of cornice and member, it is 164 feet high; the door is seven feet by 31 feet; the window-shutters, two pair, are 7 feet by 4 feet; the check-boards round them come 11 foot below the shutters, and are 14 inches in breadth; the lining-boards round the door-way are 16 inches broad; the door and window-shutters, being wrought on both sides, are reckoned work and half, and paid for accordingly; the chimney 31 feet by 3 feet, not being enclosed, is to be deducted from the superficial content of the room; and the estimate of the charge is re

8 inches about, and 14 feet bigh; but is rendered between quarters: the fathing and plastering will be 8d. per yard, and the whiting 2d. per yard. What

will the whole come to? Note.--In measuring plastering; rendering between quarters,

there is commonly a fifth part of the whole area deducted; but when rendering between quarters is whited or coloured, there is commonly a fourth or fifth

[ocr errors]

part added to the whole area, for the sides of quarters and braces, &c.

III. FLOORING, PARTITIONING, ROOFING, TILING, &c. is mea

sured by the square of 100 feet.” IN these measurements the dimensions are taken by a rod of ten feet long; and therefore the result is in squares of 100 square feet each.

Hence dividing the area in square feet by 100, the quotient will be the nurnber of squares required.

EXAMPLES. (12) In 1204 feet in length, and 124 feet in height of parti

tioning, how many squares?: (13) What difference is there between a floor: 28.feet long,

and 20 broad, and two others that measure 14 feet a. piece by 10? and what do all three come to, at 21. 55.

per square? (14) Suppose a house of three stories, besides the ground-floor,

were to be foored ai sl. 10s. per square; the house measures 31) ftet by 204 feet; there are eight fireplaces, whose measures are, four of 6 feet by 5, and four of 41 feet by 4, and the well-hole for the stairs is

10 feet by 81; what will the whole come to? (15) How many oaken planks will floor a room 604 feet long,

and 334 wide, supposing the plank 15 feet long, and

1 wide? (16) Suppose a house measures, within the walls, 64 feet in

length, and 36 feet in breadth, and to be of a true pitch; what will it come to roofing, at 12s. 6d. tbe

square? (17) Suppose I employ a person to thatch a barn, which is

70 feet long, and 30 deep; I demand how many squares are contained in the whole ; also what it will

come to at 10s. 8 d. per square ? (18) What will the new ripping an out- house cost, that

measures 324 feet long, by 221 broad, upon the flat, at 158. the square; the eaves' boards projecting 10 inches

on each side? Note.--In tiling and roofing, it is customary, to reckon the

flat and half of any building within the walls to be

the depth or width of the roof of that building when the said roof is of a true pitch, that is, when the rafters are of the breadth of the building. But when the roof is more or less than the true pitch, they mea. sure from one side to the other.

IV. BRICKLAYERS' WORK is measured by the rod, of 2724

square feet.

THIS work is always valued at the rate of a brick and a half thick; and if the thickness of the wall be more or less, it must be reduced to that thickness by the following

RULES. 1. Multiply the area of the wall in feet, by the number of

balt bricks in the thickness the wall is of: divide the product by 8164, and the quotient will be the content in

rods; or, 2. Multiply the area of the wall by the number of half bricks

the thickness the wall is of; the product, divided by 3, gives the area in feet, which divide by 2721; the quo

tient will be the rods required, Note.The fraction | in rule 1, or in rule 2, is rejected in

favour of the workmen.

EXAMPLES. (19) There is a brick wall 470 feet round, and g; feet high,

and three bricks thick. How many rods does it con

tain? (20) A gentleman built a wall round his garden, which is

840 feet, and 9 feet high, and 21 bricks thick. How many rods does it contain, and what will it come to at

41.195, 6d. per rod ? (21) The end wall of a house is 24 feet in breadth, and 40

feet to the roof; of which is two bricks thick, * more l brick thick, and the rest i brick thick. Now the gable rises $8 course of bricks (4 of which usually make a foot in depib), and this is but 4 inches, or balf a brick thick, What will this piece of work come to at 5l. 109, per statute rod?

QUESTIONS for Exercise in SUPERFICIAL MEASURE. fi) An elm plank is 141 feet long, and I would have just a

yard square slit off. At what distance from the edge

must the line be struck ? (2) Having a rectangular marble slab, 58 inches by 27, I

would have a foot square cut off, parallel to the shorter edge. I would then have the like quantity divided from the remainder, parallel to the longer side: and this alternately repeated will there be not the quantity of a foot left. What will the dimension of the remainder

be? (3) Being about to plant 10584 trees equally distant in rows,

the length of the grove nust be six times the breadth.

want a seantling just as big again, aud that shall be

three inches thick. What will the other dimensions be? (5) I have a square girder, 19 inches by 11; but one quarter of the timber in it (provided it be 9 inches deep) will
